We are building a ad-hoc component with acitiviti. Is it possible to model a process where only one Tasks of parallel Taks should be completed by the user? Like on the attached image, the process will end if one user complete task 1, 2 OR 3.
You can use a multi-instance-task (see user guide for details) in order to have the same task be available for eg. 6 people. Using the completionCOndition, you can move the process on when 3 tasks have been completed (for example).
